Office 2015

One night, ordinary white-collar worker Mr. Kim (Bae Seong-woo) goes home and murders his whole family. With Mr. Kim still on the loose, his office colleagues - who have not exactly treated him kindly over the years - are now looking over their shoulders in fear. The sole exception is Mi-rae (Ko Ah-sung), the lowly bullied intern who was the only person that showed Mr. Kim a trace of kindness.
